Abstract: The title compound, {[Cd(C₁₆H₂₀N₆O)₂(H₂O)₂](NO₃)₂·2H₂O}_n, contains a Cd^II atom, a 4-tert-butyl-2,6-bis(1,2,4- triazol-1-ylmethyl)phenol ligand (L), a nitrate anion and two water molecules in the asymmetric unit. The Cd atom resides on a crystallographic inversion centre, and the coordination about the Cd atom is distorted octahedral, formed by four equatorial N atoms from the triazole N atoms of four different L ligands [Cd-N = 2.295 (3) and 2.395 (3) Å] and the O atoms from two axial water molecules [Cd-O = 2.287 (3) Å]. Two Cd atoms with two L ligands form 24-membered M₂L₂ metallacycles along the a-axis direction, generating a double-stranded one-dimensional cationic chain. Inter- and intramolecular O-HO/N hydrogen-bond interactions form a three-dimensional supramolecular network.
